Curiosity captures sunrise panorama over Mars yardangs

Curiosity captured a panorama showing sunrise light on yardangs on 2026-08-11. The scene was recorded at 08:30 local Mars time during sol 4982.

The panorama was assembled from six separate images joined into one view. It was processed without white balancing, and a crop zooms in on distant yardangs.

Yardangs are wind-carved features. The yardang layer is roughly 10 miles across, or 16 kilometers across.

Scientists are eager for more information on the yardang layer's formation, and its origin is not entirely certain. One theory is a pile of volcanic ash.

Mount Sharp is 3 miles tall, or 5 kilometers tall. It consists of distinct layers deposited in a stack, and the stack ends with the yardang layer.

Those layers record separate periods of Martian history and indicate ancient lakes and streams once covered the area billions of years ago. Curiosity is reading climate history from the layers, and erosion may have started before this layer was deposited, leaving a gap in an otherwise continuous climate history record.

Curiosity has been ascending Mount Sharp since 2014 and is climbing the mountain's shoulder. Its elevation has reached 0.6 miles, the most ever climbed on Mars, and it has also reached 1 kilometer of elevation. The rover is in the second year of its fifth extended mission, which began by exploring spiderweb-like boxwork ridges.

For readers tracking lunar and planetary surface operations, the update shows a long-running robotic mission still climbing, imaging, and investigating layered terrain at record elevation on Mars.

Mount Sharp's layers preserve evidence of ancient lakes and streams, while the yardang layer may mark a gap in an otherwise continuous climate history record. Scientists' uncertainty about how the layer formed makes the current observations significant.

The rover's robotic arm will collect data on the yardangs.

During most of the next year or so, Curiosity will drive through layers enriched with sulfates and carbonates.
